To all 'whom t 4m Ly concern.' 1 I' Be it known that I, AUGUST Karim, a citiv zenof the United States, and resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Pipe-Supports, of which the following is a specification, and which are illustrated `in the accompanying drawings, forming a part thereof.

The invention relates to pipe supports and more-particularly to supports for those ipes which are employed for conveying a eating fluid and wherein provisionis to be made for loi;agitudinalmovement of the pipe due-to itsexpansion and. contraction upon changes iii temperature.

The object of the invention is to provideV a pipe support which' shall be eicient in service and'which is so constructed as to facilitateits erection at the lace -of use.

'lhe invention is eXempli ed in the structures which are hereinafter described and which are illustrated in the accompanying drawings, whereini y Figure 1 shows in side elevation a -form oftrapeze support vembodying the features of the improvement provided by the invention; Fig. 2-is a front elevation of the same, some ofthe parts being shownin section;

Fig. 3 is s ii'i'iilar to Fig. 1,V but shows a slightly modified form of construction; Fig. 4 is :i detail perspective view showing a forni of saddle block which may be used for supporting the pipe; and Fig. 5 is a front' elevation showing a bracket forni of Support embodying the'features of improvenient provided by the invention, the pipe supported thereby being shown in section.

A pair of pipes desired to be supported in substantia-illy horizontal position are repre- -entcd :it 10 and 11, in Fig. 2 of the drawings. For the. purpose of illustrating the adaptability of the invention for supporting pipes of dii'erent sizes, one of the pipes represented in Fig. 2 is of much larger si'z-e. than the other. VIn carrying outthe invention, a pair of opposit'ely facing saddle blocks, .as 12. 13, and 111, 15, are located beneath each of the pipes to be supported and at opposite sides of its center line. These saddle. blocks are preferably so formed as to be clamped in position upon any form-of supporting member extending transversel below the pipes. As shown, each of the sa dle blocks 12, 13. 11 and 151is providedwit-h a tubular forni of base 16 having a clamping Specification of Letters Patent..

screw 17 extendin tliereinto from one side whereby it may slipped onto a round member, as the pipe section 18, and clamped thereon in the desired adjusted position.

Each saddle block forms a partial for the pipe through being provided with an arm` 19 which extends obliquely upward from the tubular base portion 16, andhas its upper face 20 curved or hollowed out to` 65 substantially conform to the adjacentportion of the face of the pipe. Provision is made for longitudinal movement of the pipe on the saddle blocks by forming the face 2O of each saddle block with aball socket 21 7o and mountin therein an anti-,friction ball 22. Preferab y the ball socket 21is of such depth as to effectually retain the ball 22,- while'still leaving a part of the ball pro jecting beyond'the face 2O to engage the 75 pipe.

It has been found inpractice that in the longitudinal movement of the pipes, as 10, upon the saddle blocks, vduring the expansion or contraction of the pipe, a considerable amount of scale is vstripped from the surface of the pipe by the engagement of the ball 22 therewith, which scale finds its. way into the ball socket 21. To prevent such an accumulation of this scale as would interfere with the turning of the ball, a

drain opening 23 is preferably provided.

As shown, this drain opening extends from the lower part of the ball socket 21 through the arm 19 to an openingupon the lower? 950 Any scale or otherdirt which finds its way into the ballsocket-'Ql about the ball 22 is accordingly worked into'i'- the drain passage 23 by the continued turn ing of the ball and is eventually discharged l from the lower end of the drain openingat the under side of the arm 19. In'thlsiwa the ball socket is kept free from'a`fn..3;f

The use of :separate saddle blocks,i`a s 12,

A13, for supporting the pipe at'dpposite sides o f its median plane, permits of the emplovment of a single form of saddle blocks for supporting different sizes of pipe. For this purpose the two saddle blocks are so posi! -tioned upon the supporting member, as l8,as to properly receive. the 'pipe lupon the antifriction balls 22 of the two saddle-members. 11i,

When the pipe is of considerable size,l shown at 10 in Fig. 2, the two saddle blocks,-

I t-ioned somewhat closer together.

as 12, 13, will be located some distance apart.. For supporting a smaller pipe, as 11, the two saddle blocks, as 14, 15, will be posi- This appears from an inspection of the relative positions of the saddle blocks 1Q, 13 and 1l, 15, shown in Fig. 2. To facilitate the erection of a pipe support at the place of use, bracket caps, as 24, 25, are provided for the opposite ends of thl pipe section 18. Each of these bracket caps has a threaded socket 26 for reoeiving the pipe end. 1t also has an ape-rtured lug or eye 27 extending longitudinally outward from the threaded socket portion 26.

`In the form of support shown in Fig. 5 of the drawings,- a pipe section 38 is used. For engaging the pipe, as 29, the pipe section 28 is equipped with saddle blocks .30 and 81 similar in construction to the saddle blocks 12 and 13 shown in Fig. 2. The ends of the pipe section 28 are fitted with bracket caps 32 and 33 of the form shown at 24 and 25 in Fig. 2. In erecting a support at the place of use, the workman will cutoft' the pipe section 18 or A28 to the required length and thread its ends. He'will then pass the tubular base portions 16 vof the required number ofsuddle blocks, as 12, 13, 14 and 15, or 30 and 31, onto the pipe section, and will tit the bracket ce 24, 25, or 32, 33 upon its opposite ends. *or this purpose he will not require other tools than a pipe cutter and a die of the form commonly at hand in places where erecting of the sort under consideration is to be accomplished.

The tra eze form of support illustrated in Figs. 1 andJZ of the drawings is completed by mounting a bolt, as 34, 35, in the apertured lug 27 of each of the bracket caps 24, 25. These bolts are each supported in a. hanger 36. As shown, each of the hangers 36 is made from a single piece of strap iron bent to the form illustrated in Fig. 1, the ends of the strap iron being overlapped at the lower end of the hanger, as indicated et 37, 38, and connected by the bolts 34 and 35 respectively. A truss form of hanger designed to resist any swaying of the support during longitudinal movement of the pipes 10 and 11 is thus produced. he hangers 36 may each be secured to the ceiling beneath which the pipes 10, 11 extend, as'by passing lag screws 39 through the mid-length of the stre iron from which the hanger is formed. If esired, the stiffness of the hanger may be increased by the use of a stay iron 40 beneath the head of each of the lag screws 39.

This stay iron is shown as having its oppoA site ends exed to engage the angles, as 4-1, 42, of the .hanger 36, the intermediate portion of the' stay iron 4() being spaced apart from the adjacent portion of the hanger 35 by the use of a bushing 43 sleeved onto the leg screw 39 between the stay iron 4G and l the adjacent portion of the han er 36. In some instances it may be desiralgale to snp-` port pipes, as 44,- beneath a ceiling having beams, as 45. lVhen the lower edge of the beam is formed with oppositely rdirected flanges, as 46, 47, the-pipe support will be conveniently formed in the manner shown in Fig. 3. This figure shows a `trapeze support identical in construction with that illustrated in Figs. `1 andn2, except that in lieu of the hangers 36, hangers of the form represented at 48 are employed. The hahger 48 is composed of a pair of strap irons' 49, 50, each having its upper end over-turned, .as indicated at 51, 52,l to engage the corresponding. flanges 46, 47 ofthe beam 45. The lower ends of the strap irons 49, 50 are over-turned and overlapped, as indicated at 53, 54, to receive a bolt, as 34. Hangers of this form may be securely clamped upon a beam, as 45. For this purpose, a bolt 55 is passed through the strap irons 4.9, 50, immediately below the flanges of the beam 45, to clamp these ironsagainst the flanges of the beam. A rigid construction is provided by the use of a bushing 56 sleeved onto the bolt 55 between the strap irons 49 and 50.

The form of hanger shown in Fig. 5 may be conveniently used lWhere a pipe, 1151,29, is to be supported from a side wall. In this instance, bolts 57, 58 are mountedin the apertured lugs 27 of the bracket caps 32, A wall bracket form of support is then produced by the use ofstrap irons 59 and 60, each having an over-turned higher end v61 for connection with one of the bolts 57, 58. The strap iron 60 is secured in upright position against the wall, as by the use of lag screws 62, 63. The strap iron 59 is connected to the strhp ,iron 60 at its lower end, as at 64, and extends obliquely upward therefrom, to its point of connection with the bolt 57.

In the use of any 'of the constructionsA shown, the part-s of the hangers, as 36, 4S, u( and the strap irons 59, 60, will preferably be out to length and formed into shape at the Shop. if then the'workmnn is sup lied with a quantity of these hangers or braciet pieces, as also with a number of saddle blocks, as 115 v12, 13, and bracket caps of the form shown at 24, 25, he will be completely equipped to produce any of the forms of supports which are shown,lmerely by theuse of his redular I equipment of tools and such o idinary :bolts 12o and nuts and lengths of pipe as' will be available at the place of erection. The constructions therefore provide pipe,supports which may be conveniently erected, and they are further desirable in that they serve to effec` tually support the pipe without interfering with its longitudinal movement. By locating the bail 22 adjacent the ,lower end of the arm 19 of the saddle blocks, as 1Q, 13; that part of the arm which extends beyond the 13o y ball serves as a guide to prevent displacement of the ipe from its seat in the event of its bein sexed, as b an unequal expansion of di erent parts o the pipe.
